Optilumen RKS Universal Fluorescent Fixture Retrofit Kit. Easily converts most all your existing residential and commercial 4 and 8 foot T5, T8 and T12 linear fluorescent light fixtures into an integrated LED light fixture. This retrofit kit works with the earliest to the latest versions of ceiling mount, four-foot and eight foot fluorescent light fixtures, regardless of the style, manufacturer or existing ballast type including linear high-bay, strip or wrap fixtures and even chain suspended shop lights. Since the retrofit kit contains the LED driver, there is no guess work to determine if it is compatible with your existing fixtures’ magnetic or electronic ballast. Super simple installation in 3 easy steps: 1). Remove existing bulbs and ballast. 2). Attach magnetically backed driver and connect to AC power source. 3). Attach magnetically-backed LED strips and quick connect to Y-harness. If your fixture isn't steel, no worries, the kit is pre-drilled and comes with mounting screws. The fixture is DLC listed to qualify for commercial lighting rebates and special incentives in certain regional areas.- One retrofit kit converts a 4 ft. fixture with 4 lamps or two 8 ft. fixtures with 2 lamps; See our Optilumen RKS Selection and Savings Chart

Comfortable, sturdy, waterproof
Size: 9.5, Color: Black/Black
Loce, love, love these boots. Have walked ten miles with no foot pain around NYC. They go with everything and and are so comfortable. As they are waterproof/resistant, they get a little warm in high temps, but perfect three-season boots.

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days.
Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!

Definitely worth the price
Size: 6.5, Color: Black/Black
Absolutely love these boots! I originally bought them to wear in NYC in December & they did not disappoint. They were comfortable, cute, durable and worked well in the slush/snow. The traction on the bottom is also nice! They kept me warm with wool socks. I wear them almost daily now. Perfect for everyday. easy to wear with variety of outfits. Good every day shoe.
